Processor
•
The PGA Socket 478
•
Supports
Intel Pentium 4 series
CPUs
•
Supports up to 400/
533
MHz Frontside Bus
Note:
SiS 645DX Northbridge supports up to 533MHz
Frontside bus.
The SiS 645/SiS 645DX and SiS961 chipsets are based on an
innovative and scalable architecture with proven reliability and
performance. A few of the chipset’s advanced features are:
•
A low 2.5-volt DDR SDRAM power consumption which
makes it an excellent solution for notebooks and desktops
with a small footprint
•
Support for a 4xAGP interface providing vivid 3D graphics
and video performance
•
An ATA 100 interface on the chipset, which helps boost
system performance by providing a high-speed connec-
tion to ATA 100 Hard Disk Drives, delivering maximum
sustained data transfer rates of 100 MB/sec
•
Built-in multithreaded I/O link used to enhance perform-
ance, providing enough I/O bandwidth for throughput up
to 1.2 GB/s
Additional key features include support for six USB ports, an
AC 97 link for audio and modem, hardware monitoring, and
ACPI/OnNow power management.
